i personally wouldnt have run it on top of the intake but that plastic peice on top of the actual intake will melt well before your wire will. been there seen that!
that is the im if i'm not mistaken, and composite manifolds dont get very hot but i would still reroute it for 2 reasons: better safe then sorry, and it just doesn't look that good (but theres a cover missing iirc).
